Description

Twins that dance in and out of phase, never completely together but never fully apart, bound to each other in the infinite universe.

Castor & Pollux is a Roland Juno-inspired oscillator. It contains two digitally-controlled analog oscillators implemented using a faithfully modernised version of the original Juno 106 design. Like its inspiration, it can give you that wonderful ‘80s sound with independent and mixed ramp, pulse, and sub outputs. But the twins do not stop there- the second oscillator can be used to layer in thick detuned sounds, harmonically complex hard synced waveforms, or as a fully independent second voice.

The cherry on top is the internal LFO that can apply subtle pitch shifting to the second oscillator. This gives a sound that echos back to the Juno’s legendary chorus while giving the module its own unique voice.

All surface-mount parts are already soldered and the mainboard has been programmed, tested, and calibrated.

Features

  • Two separate oscillators with a 7 octave range

  • A flexible set of outputs (9 total):

    • Separate ramp, pulse, and sub outputs for each oscillator

    • Each oscillator has its own mixer to combine the ramp, pulse, and sub waveforms into a single output

    • A combined output with a cross-fade mixer

  • Pitch CV in (0v to 6v) and pitch offset knobs (-1 oct to +1 oct) for each oscillator – the pitch offset knobs have a non-linear response which makes it easier to tune the oscillators.

  • Pulse-width CV in and knob for each oscillator

  • Hard sync mode that syncs the second oscillator to the first

  • Built-in low-frequency oscillator (LFO) that can be used to modulate the pitch of the second oscillator. It can also be used to provide pulse-width modulation to both oscillators.

  • Power consumption: +12v 100mA, -12v 35mA, (+12v can be reduced to as low as 65mA by reducing the LED brightness)

  • Depth: 25mm

  • Width: 14HP

100% open source hardware, firmware, and software
